A procedurally generated fractal cathedral rises from recursive architectural elements, featuring repeating towers, transepts, and glowing rose windows that diminish in scale with each iteration. Built with Three.js, the structure uses `BoxGeometry`, `CylinderGeometry`, and custom `BufferGeometry` meshes with `MeshPhongMaterial` surfaces. The scene includes directional and ambient lighting through `DirectionalLight`, `PointLight`, and `AmbientLight` objects, while `OrbitControls` enable interactive camera orbiting, zooming, and panning.
